IC200ALG331
Analog Output Module, 16 Bit Voltage/Current, 1500VAC Isolation, 4 Channels
Operation
The default parameters of this module can be used in many applications. The module can
be software-configured when it is installed in a VersaMax PLC system, or an I/O Station
controlled by a Network Interface Unit that is version 2.0 or above.
Output Defaults
The module requires both logic and module 24 volt power supplies to produce an output.
Subsequent loss of power or communication will produce output states as determined by
the configuration. These are:
Power and configuration states
Field power, no logic power, not configured
Field and logic power, not configured
Field and logic power, configured
Module defaults due to loss of
communications or other cause.
Loss of backplane power after configuration
Communication returns without loss of
Field Power
Calibration
The module is calibrated at the factory. For most applications, no further calibration is
required. It is possible to perform recalibration in either of the following ways:
By changing a module's scaling so its scaled data agrees with metered values.
By sending the module a recalibration message as described in the PLC User's
Manual.

Output condition
All outputs 0
All outputs 0
Outputs are scaled and follow program data
Outputs are set to configured default: value or
Hold Last State.
In I/O Station with NIU, outputs are set to 0.
Outputs are set to Hold Last State if configured
for Hold Last State operation, or to 0 if "default"
was configured. A configured default value is not
available to the module if backplane power has
been lost.
In I/O Station with NIU, outputs set to 0.
Outputs resume operation after configuration.
